Causes of Rotator Cuff Tendonitis
Repetitive Muscle Use
Inflamed tendons are often caused by small, repeated movements over a period of many days, weeks, or even months. These activities put stress and pressure on your muscles, which leads to localized inflammation and micro-tears. Determining which tasks are causing the issue is important to prevent the occurrence of rotator cuff tendonitis. Some sports can increase the risk include tennis, golf, swimming, volleyball, baseball, or badminton. Work-related triggers might be gardeners, construction workers, carpenters, painters, and other jobs requiring the use of shoulders repeatedly. [3]
